The hydrogen embrittlement sensitivity of duplex stainless steel with different phase fractions evaluated by in-situ mechanical testing Ghent University
The influence of the austenite (gamma) phase fraction on the hydrogen embrittlement of duplex stainless steel is investigated. Heat treatments are performed to create two duplex stainless steel specimens, containing 50% and 44% of austenite, respectively. Mechanical testing with and without hydrogen charging reveals that significant embrittlement occurs regardless of the austenite fraction. A higher austenite fraction results in a reduced ...
Quantifying thermoset polymers healing efficiency: a systematic review of mechanical testing Vrije Universiteit Brussel
The study of fracture behavior of self-healing polymers is the key-tool that issues the efficacy of the advanced healing functionality. Damage mechanisms of autonomously healed polymers resemble the adhesive joints one. Thus, well-established fracture testing configurations of adhesive composites are acquired and adopted in order to monitor the damage initiation (cracking) that calls for healing recuperation. As soon as healing is achieved the ...
Microscale and macroscale deformation behavior of electrospun polymeric nanofiber membranes using in situ SEM during mechanical testing Ghent University
Prebending of Osteosynthesis Plates Versus Screw and Cerclage Fixation for Os Acromiale or Acromion Fracture; the 3D Technique and Mechanical Testing Hasselt University
Three-dimensional applications are on the rise in medicine, mainly to make treatment more patient specific. This study compares the in vitro outcome parameters of 2 surgical techniques: hollow screws with cerclage fixation (HC) versus patient-specific plate osteosynthesis (PO). The techniques were tested on scapulae of 5 fresh-frozen cadavers as a treatment for symptomatic os acromiale or acromion fracture, to assess ultimate failure strength, ...
An optimized non-destructive protocol for testing mechanical properties in decellularized rabbit trachea University of Antwerp KU Leuven
Successful tissue-engineered tracheal transplantation relies on the use of non-immunogenic constructs, which can vascularize rapidly, support epithelial growth, and retain mechanical properties to that of native trachea. Current strategies to assess mechanical properties fail to evaluate the trachea to its physiological limits, and lead to irreversible destruction of the construct. Our aim was to develop and evaluate a novel non-destructive ...
The application of sonic testing on double-leaf historical Portuguese masonry to obtain morphology and mechanical properties KU Leuven
© 2019, RILEM. In order to perform a conservation or repair intervention of a historic building, knowledge of the mechanical properties of the historical materials and building components is essential. Obtaining these properties should be performed inflicting as little damage to the historical fabric as possible. Methods to do so are defined as non-destructive test methods (NDT). The paper investigates the use of sonic testing (NDT) on ...
About Puncture Testing Applied for Mechanical Characterization of Fetal Membranes KU Leuven
Puncture testing has been applied in several studies for the mechanical characterization of human fetal membrane (FM) tissue, and significant knowledge has been gained from these investigations. When comparing results of mechanical testing (puncture, inflation, and uniaxial tension), we have observed discrepancies in the rupture sequence of FM tissue and significant differences in the deformation behavior. This study was undertaken to clarify ...
Mechanical characterization of masonry on the macro scale from experimental testing and numerical meso scale modelling KU Leuven
© 2018 The International Masonry Society (IMS). Limited experimental data of mechanical properties of brick masonry are available in the literature, especially for those properties that determine the cracking behaviour, such as tensile strength and fracture energy. Moreover, the cracking behaviour is influenced by several other factors such as the type of components, bond type, size of the element and loading conditions. Therefore, the aim of ...
